Constantine enacted another change that helped accelerate the fall of the Roman Empire. In 330 C.E., he split the empire into two parts: the western half centered in Rome and the eastern half centered in Constantinople, a city he named after himself.
Most times the history of the Empire is divided in three periods. The first of these, from 330 till 867 CE, saw the creation and survival of a powerful empire. During the reign of Justinian (527-565 CE), a last attempt was made to reunite the whole Roman Empire under one ruler, the one in Constantinople.
